Specifying IP Address Netmasks


Some commands call for the specification of an IP address netmask. The Netvisor ONE supports both Classless Inter-Domain Routing (CIDR) and subnet notations.


For example, to specify the range of IP addresses from 192.168.0.0 to 192.168.0.255, you can express as:


  • IP address: 192.168.0.0/24 or
  • IP address: 192.168.0.0:: 255.255.255.0 (netmask)


Here is a sample of the CIDR to subnet notation mapping:


CIDR

Subnet Mask

/24

255.255.255.0

/25

255.255.255.128

/26

255.255.255.192
